Abstract

The invention discloses a film, a waterproof coiled material and a lap joint method. The film comprises a first plane material, a PVDF film and a second plane material which are bonded in sequence. The waterproof coiled material comprises the film and a modified asphalt adhesive layer bonded on the second plane material. The lap joint method comprises the steps that the first plane material and the modified asphalt adhesive layer are sequentially lapped together, wherein the waterproof coiled material comprises the first plane material, a first composite adhesive layer, the PVDF film, a second composite adhesive layer, the second plane material and the modified asphalt adhesive layer which are sequentially arranged from the surface layer to the bottom layer. The film is provided with three layers, so that a certain lap joint foundation can be provided for the waterproof coiled material. According to the waterproof coiled material, the first plane material in the waterproof coiled material is bonded with the modified asphalt adhesive layer, so that quick lap joint of different waterproof coiled materials can be realized in the construction process. The waterproof service life can reach 25 years, the risk of waterproof leakage repairing can be reduced along with the increase of the service life, the waterproof quality of a building is improved, and the use amount of the modified asphalt mastic is reduced.

Description

technical field [0001] The application belongs to the technical field of waterproof coiled material, and in particular relates to a membrane, a waterproof coiled material and a lapping method. Background technique [0002] Existing waterproofing membranes include membranes using PVDF (Polyvinylidene difluoride, polyvinylidene fluoride) composite membranes, the bottom layer of which is made of modified asphalt glue, and short-side laps are used during construction. Specifically, the above-mentioned PVDF waterproofing membranes The bottom layer is lapped to the surface of the PVDF waterproof membrane. Since the adhesive force between the modified asphalt glue and PVDF is not enough, it is usually necessary to use special tapes to bond different waterproof rolls together to prevent waterproofing. However, the existing construction scheme has low construction efficiency and the finished product after lapping is not beautiful enough, which is easy to make mistakes and cause leaka...
